SMOKEJLIESS ORCHARD-HEATER.

Specication of Letters Patent.

Application tiled March 27, 1917.v Serial No. 157,662.

il 'o all Iwhom t may concern,

Beit known that I JOSEPH PAx'roN' S1Mr` soN, a citizen of the ZUnitedStates, residing Pomona, in the county of Los Angeles California', haveinvented new and useful Improvements in Smokeless Orchard-Heatcrsyofwhich the following is a specification.

y invention relates to orchard heaters, my object being to improve thedetails of construction with a View of .producing more perfectcombustion, and my invention consists in the novel features hereinshown, described and claimed.

Figure 1 is aview in side elevation illustrating the heater assembledand ready for use.

Fig. 2 is .a view in plan illustrating the heater shown in Fig. 1 andparticularly disclosing the design of the bale wall within the fuelcontainer.

Referring more particularly to the drawings, 10 indicates a liquid fuelcontainer which is here shown as rectangular in shape and formation andadapted to rest dat upon the ground. This container is provided with acover 11 formed with openings 12 and 13 at its opposite ends. Theopening 12 cylindrical sleeve 14 which extends upwardly and is coveredby a telescoping cap 15 positioned thereover. The

of perforations adapted to adjustably register with similar perforations16 formed through the .cylindrical side wall of the cap. An operatisfixed to the top of the cap and provides adequate means for permittingthe cap to be rotated upon the sleeve in a manner to regulate the draftwithin the container 10. The handle 17 also permits the cap to bereadily removed from the sleeve when it is desired to ll the container.

The openin 13, at the opposite end of the cover 11, 1s fitted with avertically extending pipe 18. A. due drum 19 is secured at the upper endof this pipe and in com- This drum is of enlarged dimensions and isformed with a series of perforations 2O atits lower end through which adraft will pass toV unite with the gaseous fuel which passes upwardlythrough the pipe 18 and into the drum 19, thereby causlng proper combus-I tion thereof. ,A baille plate 21 1s positioned within the .drum

v19 and spaced a distance from the opening through which the drumcommunicates with the pipe 18. This plateV through the ap? prevents anexcessive draft paratus and also retards the gaseous fuel as 1t passesinto the drum so that it will more properly unite with the oxygenpassing into the drum through the o enings 20 and thereafter produce amore eliicient combustion of the gas. It will be noted that the lowerrow of perforations-20 are positioned beneath the horizontal plane ofthe baille plate" 21 and will cause combustion therebeneath in a mannerto effectively eliminate the accumulation of carbon which wouldotherwise collect and in time render the apparatus inoperative. The mainportion of the drum 19 extends upwardly a considerable distance.

and carries away the gases reduced by the combustion of the fuel. seriesof stay rpds 22, 23 and 24 are pivotally fixed to the tend within theground around the bottom of the fuel reservoir in a manner to firmly suport the drum.

n operation, fuel is placed within the reservoir 10 and allowed toencircle around a baille wall 25 which is positioned at a point adjacentthe vertical pipe 18 and the opening 13 through the top of thereservoir. This wall forms lside passages 26 and 27 around which the gasand flame may circulate and which will permit the gas produced in thedevicel to pass lto the drum 19. When the apparatus is used, the cap 15is removed andthe liquid fuel within the reservoir is ignited. The capis then placed in position over the sleeve 111 and regulated so thatthere will be suiicieut oxygen within the reservoir to produce ropergenerating combustion. Care is ta en to see that but a Small draft willbe established through the generated gas and smoke through the series ofperforations 2O which extend circumferentlally around the wall of thedrum 19. The combustion of the gas within the drum will rapidly raisethe temperature of the drum and impart a largeamount of heat to Patenteddan. 15, 1918.'

sldes of the drum 19 and are adapted to ex-v im l the surroundingatmosphere, thereby heating the orchard without producing a smoke.

I claim:

1'. In an orchard heater, an oil container consisting of a long flat boxadapted to rest upon the ground and provided with a cover having aninlet opening at one end and an l outlet opening at the other end, abaffle wall wardly from the outlet opening, a drum.

mounted upon the upper end of the pipe; said drum being considerablylarger than the pipe; and a baffle plate mounted horizontally in thedrum above the end of the pipe; there being perforations-all the wayaround the drum below and above the baile plate.

2. Inan orchard heater, an oil container consisting of a long .fiat boxadapted to rest upon the ground and provided with a cover having aninlet opening at one end and an outlet opening at the other end, abaiiie Wall mounted crosswise of the box in front of the outlet openingand extending the height of the box and leaving openings upon each side,a cylindrical sleeve extending upwardly around the inlet opening, a caplitting upon the Sleeve; there being registering perforations throughthe cap and sleeve; a handle for rotating the cap, a pipe extendingupwardly from the outlet opening, a drum mounted upon the upper end ofthe pipe; said drum being considerably larger than the pipe; a baileplate mounted horizontally in the drum above the end of the pipe; therebeing perforations all the way around' the drum below and above thebaffle plate; and a series of stay rods pivotally xed to the sides ofthe drum and adapted to extend outwardly to the ground.

In testimony whereof I have signed my name to this specication.

JOSEPH APAXTON SIMPSON.
